U can find the common ratio by dividing the 2nd term by the first term
r = -9/3 = -3
an = a1 * r^(n - 1)
a1 = 1st term = 3
r = common difference = -3
now sub
an = 3 * -3^(n - 1) <== ur formula
domain : all integers where n > = 1 <==

Answer:
x=0
Step-by-step explanation:
2x-3x=9-3-6
-x=0
x=0
Since this is a right triangle, we can use our trigonometric functions to solve for x.
Since we know the adjacent side and hypotenuse, we will use cosine.
Based on the function
, we can solve for x. The adjacent side is 7 and the hypotenuse is 12. Plugging this in, we get
.
Now, we must use our inverse trigonometric functions to solve for x:
The inverse cosine and cosine on the left side cancel, leaving you with:
Answer:

35+11 = 46
46×14 = 644
644÷2= 322
